Discolouration

I bought a trio of long fin commons about 7-8 cm

I've had them for about 4 / 5 weeks, My fish keep spawning but these guys havent yet.

I noticed yesterday that the males shoulder has turned to albino colour.

Its a common but from the back of the head 1 or 2 cm down the back its lost all pigment or colour.

Do u guys know what this might be ?

Hi,have you got a photo please?

Photo isnt working

When I click host it nothing happens ??

I havent tested my water in a while
BUT,
All my other bristlenose are fine they are breeding prolifically

One of my albinos spawns and within a few days hes back in his cave fanning again.

I have possibly hundreds of fry up to about 3 cm growing really well and fast.

I do weekly water changes as well as whenever a low front is approaching and the tank is heavily planted.

Hope this works

Hi,the photo isn't working unfortunately.

when u go to photobucket link click on fish file

Hi,before you do anything at all you need to test your water and give the readings,that is most important.Here is a link that i think will help you out,try upping the temp and adding aquarium salt first before adding other meds (you may want to quarantine first but the tank may need treating too) and see how that goes.If it doesn't clear up then medicate with the recommended meds.

P.S For bristlenoses i only add 1 TEAspoon aquarium salt per every 2 gallon.

thx will do

Dont know if the discolouration is still there or not

But I spotted him in one of the caves yesterday and he is still in there today

Finally the long fins have started

Hi,did you do anything to treat him?

I havent treated the water with anything reluctant because all the other inhabitants seem fine

My male common LF will get white patterning at the base of his head and his shoulder area. The patterning can change from a bright white to almost no pattern at all. I use to notice it a lot when he lived with another adult male who was dominant over him. Now I notice it most during water changes and when I am somehow disturbing the tank. This leads me to believe that it is stress induced (in my situation at least.)

Is the discoloration fuzzy,cottony, streaked, polka dotted, ect...?
